Why do I need a Brake-Lite Relay? It stops the brake lights from functioning until the vehicle is started. This prevents the towed vehicle’s brake signal from overriding the motorhome’s turn signal. When you tow without the Brake-Lite Relay, your towed vehicle’s brake lights alone will work fine. Your turn signals alone will work fine. But if you’re braking and turning, the brake light from the towed vehicle will override the turn signal from the motorhome and drivers behind you will be unaware you’re about to turn. You only need a Brake-Lite Relay if you’re installing a supplemental towed vehicle braking system that pushes or pulls the brake pedal.
